Kötnyomaték

Kötnyomaték is a Hungarian term that translates to "torsional stress" or "torque" in English, commonly used in the context of mechanical engineering and physics. It refers to the rotational force applied to an object that causes it to twist. This force is measured as the product of the force applied and the perpendicular distance from the axis of rotation to the point of force application.

When an object experiences kötnyomaték, it undergoes deformation. This deformation is a twist or torsion along its longitudinal axis. The extent of this twist depends on the material properties of the object, its geometry, and the magnitude of the applied kötnyomaték. For example, a steel rod will resist twisting more than a rubber rod of the same dimensions when subjected to the same kötnyomaték.

Understanding kötnyomaték is crucial in designing various mechanical components. Shafts, axles, and screws, for instance, are designed to withstand specific amounts of kötnyomaték during their operation. Exceeding the material's limit for kötnyomaték can lead to permanent deformation or even failure, such as fracture. Therefore, engineers calculate and analyze kötnyomaték to ensure the safety and reliability of mechanical systems. Common units for measuring kötnyomaték include Newton-meters (Nm) or pound-feet (lb-ft).
